BoB was basically brit fighters vs lw bombers & escorts.
I'd say use the euro map (duh),
Enable spit1 free,C202 (replacement for pre-V spits, and its got no hispano) at 2 pnt perk cost , hurri1 free,hurriIID (hell, give the limeys at least 1 cannon ride
) at 2 pnt perks costfor Brits
Enable Ju88 free, Ki67 (as replacement for HE111) at 2 pnt perk cost, IL2 (replacement for STUKA) free,109E free,109F4 at 2 pnt perk cost, and 110C4 free for LW.
Brits have M16 enabled.
NO other vehicles allowed. No m3's no flaks, no tanks.
Objective of LW would be to flatten RAF fields, Fuel, ammo and troop factories.
Rebuild times would be 4X longer than normal (no resupply allowed from goons/m3's since they are disabled).
Victory conditions:
LW: 80% of RAF fields closed OR bring fuel/ammo/troop factories down to 20% each.
RAF: Dont let the LW attain their victory conditions.
